This is a discussion on Had my car since its birth.. still need help haha within the New Member Hangout forums, part of the Community - Meet other Enthusiasts category; Hey, whats up everybody, I have an 05 STI, ive only ever done basic maintenance to it. Oil change etc... ...

I have almost 70k miles and have never done a" tune up" i know that's horrible. I upgraded the clutch and flywheel maybe 20k ago. I don't know how to adjust the cluth though... think that could be it? What info would help you help me? Haha

Yeah its at idle or when i depress the clutch when preparing to stop. Its a lightened flywheel but i forget the brand... ACT maybe? How do i raise my idle? It only recently started this... think a new set of plugs and a general tune up would help alleviate this as well?

plugs and tune up won't do it. The idle needs raised. I have the ACT Streetlight flywheel as well. Since this is an STi you can't adjust the idle control cable. It needs to be done within the ECU. Is it a stock ECU?

The BOV can also cause idle problems. If you have the stock bypass valve... put it on and see if the stalling stops. If it doesn't... then I'd suggest purchasing the cobb accessport v2. It has an idle adjustment on it and it's an excuse to get a reflash to stage one. Get a bit more boost

Extra boost never hurt anybody haha. Unfortunately my stock **** is back in ohio while i've had the misfortune(haha) of being stationed in Miramar. Guess i'll just have to start savin. Another question...ikno a little "knock" is normal but is it normal to hear it much more clearly in like 2nd or 3rd. Low to mid rpms?

there may be a grinding noise if you're at 1200 rpms and trying to drive... (this engine isn't supposed to be that low of RPMs while trying to accel) but there shouldn't be a legitimate knock sound. Does it sound like engine, transmission or suspension?

Sounds alot like valves... its in the engine for sure. I was always told it was supposed to... good friends right? Haha i questioned it cause never had a car do it...but also never owned a subaru before either...

valves sound like ticking... they're especially audible at idle from outside the car.

On cold starts you can hear "piston slapping" This is normal too, but only usually with super cold weather.

That is 100% normal on our cars. Knocking is totally different. Do you think you can take a video of your engine bay so we could hear the sound? I'll be able to tell you if it's the valve tap or if it's piston slap or knocking.. They're all very different sounding.
